Went to the rollers today. Went to a new one in the area, that a mate recommended. http://s19.photobucket.com/albums/b176/h2ypr/?action=view¤t=tmp86.jpgQuite what i expected. They didnt measure the fuelling because of my wideband. What everyone think? Ross

If you held the boost the same to the redline you would have the perfect graph What ya mean? ![laugh \:D](/forum/images/graemlins/default/laugh.gif) Ross

I presume you are tailing the boost off after 5500 - 6000rpm?

erroneous 1500rpm readings as well... more torque at 1500 rpm than at 2500 rpm. OK i'm just bored now ![laugh \:D](/forum/images/graemlins/default/laugh.gif)

Thats to do with him holding the car at 1500rpm, then releasing the rollers.
The boost tails from 1.3 to 1.2 between 5k to 6k.

No question, that is the best GT28R coupe this forum has ever seen. In fact I dare say that is the most driveable/powerful combination out there...10/10 Ross Thanks dude!! Now lets see if its any good on the 1/4 mile!!! Ross

Nice power ![smile \:\)](/forum/images/graemlins/default/smile.gif) Can u give me the spec of the engine? The torque curve is going a little bit up and down between 3-4000 rpm. What EBC are you using?

I don't know the engine spec but I do know he's using a Greddy Profec B. ![smile \:\)](/forum/images/graemlins/default/smile.gif)

I dont know why it done that tbh. I would always argue that electronic boost controllers dont work the same on the rollers as they do on the road. I originally got mines setup on the rollers and when i used it on the road it was crap. Its a false load the rollers is putting on it. On the road the boost is flat.

maybe because the rollers are constantly tweaking the load every 3 miliseconds?

i agree, rollers are totally different to the road, you are probably running 150bhp on the road ![tongue \:P](/forum/images/graemlins/default/tongue.gif) come on ross give us the whole spec, I want to compare ![smile \:\)](/forum/images/graemlins/default/smile.gif)

i think this is your spec
GT28R full 3" exhaust stage 2 TI head Fully balanced engine EVO FMIC SIP GTEC2 revised Greddy EBC
that about right?
Are you running standard CR?

Its a stage 2/3 accoring to barbz.
Its not a gtech2 im running.
I dont know about the compression. I would doubt it due to the driveability off boost.

No question, that is the best GT28R coupe this forum has ever seen. I wonder what suba's got to say about that I shall clarify ![laugh \:D](/forum/images/graemlins/default/laugh.gif) The best GT28R torque/power curve goes to Ross with amazing spool and powerband ![tongue \:P](/forum/images/graemlins/default/tongue.gif) Si does have a very very nice suspension/brake kit which will be fantastic on the track ![love \:#](/forum/images/graemlins/default/love.gif)

Why oh why do RR companies insist on using different scales for power and torque
yet again, we have a torque plot that crosses the power plot at the wrong rpm
It gives a slightly skewed picture of whats actually happening
Still an impressive graph for a GT28R - would be interesting to plot my graph over the top - I bet you're making 100bhp more than me at some points I'd be up for that!! Also, what you think it does to the "picture" by the wrong switchover? I did notice that myself. Ross
